I've bought a few R4's which run on the firmware from r4sdhc.com. They work fine with sandisk micro SD but they don't recognize kingston micro SD, weird. The kingston's work fine in R4i red box flashcards. I even tried formatting the kingston micro SD with panasonics sd formatter tool, still no joy. I have a fair bit of experience with flashcards but I've never come across anything like this.

One other thing i thought was unusual was that the data transfer rate on the kingstons I have is very slow, about 2 or 3 mins for 20mb when it's about 20 seconds for the sandisk.

I have tried 4 kingston micro SD's 2GB and 4GB and they are all brand new.

Has anybody any idea why this is happening and if there is a fix

Thanks

from what ive been told the r4 sdhc is a r4 clone... i got one too and i knoticed alot of issues with it compare to my friends normal r4 card.

so far the only card ive tried with it is pny 2gb and sandisk 4gb and a samsung 2gb

all work fine, except the games tend to freeze randomly with the pny, no suprize tho as its the cheapest sd in this area :rolleyes:

But yea it being a clone is the only thing i could think of that would do that.... my friends r4 uses a kingston 2gb

So yea i know for sure mines a clone, cause everyone says it is.... Got mine off of deal extream or w/e its called
